Sustainability requirements: 3M expects suppliers to integrate environmental responsibility into operations by complying with all relevant environmental laws and maintaining necessary permits. Suppliers should manage hazardous substances, track and reduce solid waste, control air emissions per regulations, and implement a water management program for monitoring and treatment. They must also track energy use, set greenhouse gas reduction targets, conserve natural resources, and prevent pollution. Responsible sourcing of forest-based and mineral materials is required, with traceability and compliance to specific sourcing policies. Suppliers are encouraged to use ISO 14001 and UNGC principles as guides.
